DCI
Donaldson Company, Inc.
A maker of filters and filtration systems used everywhere from tractor engines to hospital labs. Its products — like PowerCore® air filters, dust collectors, and bioprocessing gear — keep construction, farming, aerospace, and life-sciences equipment running clean, sold to manufacturers and as replacement parts. The company began in 1915, when salesman Frank Donaldson rigged a tractor air cleaner out of a wire cage, eiderdown cloth, and an eight-foot pipe after watching a farmer's machine choke on Utah dust; his boss dismissed the idea, so he started his own company. That first makeshift "Twister" filter grew into one of the world's largest filtration businesses.
